City manager Daniel Keen said Tuesday that quake damage there was the biggest challenge Vallejo has faced since emerging from bankruptcy in 2011.

Keen says Vallejo suffered tens of millions of dollars in property damage and dozens were injured, including a couple who were hospitalized.

Just 10 miles from the quake's epicenter, parts of the town suffered broken windows and collapsed masonry.

Twenty inspectors and engineers on loan from the state arrived Tuesday to help Vallejo's pared-down city staff look for loose bricks and wobbly chimneys.
